Excitement is in the air at Arizona State University as graduation is upon us. One of our very own, Mike Karam, will receive his Bachelor’s degree in Anthropology from ASU today. The staff at The Center for Digital Antiquity has been fortunate to work with Mike, an undergraduate Research Apprentice, since August 2014. He excelled in his work on improving the content of archaeological data in tDAR, specifically improving access and preserving legacy data from the Dolores Archaeological Program. Mike also updated over 30 other digital files and metadata records within tDAR. He greatly enhanced the content of tDAR and provided other tDAR users with more detailed information about important archaeological investigations. Congratulations, to Mike and his family, from all of us at The Center for Digital Antiquity!

We are gearing up for the San Francisco SAA meetings and we want to see you! You can find us at our booth in the exhibit hall (#501) from 9AM to 5PM Thursday through Saturday.
We have a lot to share—first and foremost, if you haven’t seen tDAR live and in action one of our expert digital curators will be able to walk you through finding materials in the archive, as well as the simple steps necessary to preserve a digital file. We can discuss how to go about conceptualizing and creating a digital archive, or how to organize your materials in tDAR.
If you are a presenter at this year’s SAAs we have an exciting opportunity for you to experience contributing to tDAR at no cost. All 2015 SAA abstracts will be available in tDAR as citation records. Presenters are able to upload a copy of the presentation and associated data (up to 3 files totaling 30MB) to tDAR. Stop by the booth and we’ll walk you through the upload process or provide you with instructions for completing the upload at a later date. This is a great opportunity to share and preserve your archaeological data!
Budgeting your digital data archive can be a challenge, but we are here to help. Ask any of our staff for guidance on developing a budget for a grant proposal or scope of work that will ensure all of the digital material you generate is properly cared for in perpetuity. We’d be delighted to tell you about our new, reduced rates for long-term digital curation!

Modern archaeological investigations both produce and rely upon digital data: photographs taken in the field, GIS information, analytical and descriptive data sets, project reports, etc. These new data add to an existing, although underutilized, backlog of archaeological information, some of it in digital formats, some not. Without a well thought-out approach to data management, important information, whether in digital formats or not, will be overlooked or lost because it is forgotten, misplaced or damaged. Good digital data management requires attention to the means of data storage, aspects of archiving data, how data are to be preserved, and the curation of data so that is discoverable, accessible, and usable.
Digital Antiquity Staff will be hosting a workshop at the 2015 Society for American Archaeology meetings in San Francisco, on the background of data management, how good data management is organized, and tools and methods that they can integrate into their existing project and research workflows to ensure good management of digital data. Participants in the workshop will be introduced to the types of digital repositories that are available and where they can browse, access and download archaeological documents, data sets, images, and other kinds of archaeological information. Archaeologists, whether they work in CRM, for government agencies, or in academic positions, can use digital repositories to store, organize, and promote their archaeological work.
The workshop will focus on case studies and examples in tDAR (the Digital Archaeological Record). Participants will learn how to access and use resources in the repository and curate and manage CRM reports, data sets, photographs, GIS files, and other archaeologically relevant digital resources. Participants will need to bring their own laptop computer with wireless capabilities and a file (such as a report, dissertation, dataset, etc.) to upload to tDAR as part of the workshop.
Participants will receive a voucher for one free file (up to 10 MB) and a free copy of Caring for Digital Data in Archaeology: A Guide to Good Practice (for a total value of $80).We also encourage you to stop by our booth in the exhibit hall. Digital Antiquity staff will be on hand all week to answer your questions and give you a personalized tour of tDAR. You can even sign up in advance for a 15 minute meeting with one of us to ensure you don’t have to wait! Click here to access the calendar and select your time.
Katherine A. Spielmann (Arizona State University) and Tiffany Clark (Arizona State University) will be hosting a workshop to train participants in the uploading, mapping, and integrated analysis of faunal datasets in the Digital Archaeological Record (tDAR) at the San Francisco Society for American Archaeology Annual Meeting. tDAR provides an innovative and powerful approach to the synthesis of original archaeological data through the use of an analytical tool that makes it possible to integrate databases (or spreadsheets) that were recorded by different investigators using different analytical protocols. The resulting unified database can then be used to address a diversity of research questions.
During the workshop the instructors will introduce tDAR and explain what coding keys and ontologies are, and how they fit together in tDAR. They will then work with each participant to upload one faunal dataset and its associated coding key, and on mapping their coding key to the general ontologies for a broad range of faunal variables that are available in tDAR. Towards the end of the workshop they will demonstrate the integration of multiple datasets using the tDAR data integration tool.
If you register for the workshop, instructions for what you should do before leaving home will be emailed to you.

Digital Antiquity staff often get requests for information on curating, preserving and accessing digital archaeological material, and we try to share as much of our knowledge as possible through our blog, online seminars and in person workshops. Inspired by a recent conversation on Twitter, we thought we’d share resources we’ve put together and that people interested in these topics will find helpful.
Contributors to tDAR’s blog have addressed issues regarding curation, preservation and access in the selection of blog posts below:
- Dissertations in the Digital Age – Keeping Dissertation Data Alive
- Don’t Delay! The Importance of Good Digital Curation Now!
- Get Credit for Your Data: Publishing Peer-reviewed Data Papers with tDAR
Digital Antiquity and the Archaeological Data Service have also produced guidance on good practices for caring for digital archaeological data:

The Center for Digital Antiquity (Digital Antiquity) and the Maryland Archaeological Conservation Laboratory (MAC Lab) are proud to announce that digital archaeological materials associated with the archaeological collections from Department of Defense bases and facilities that are curated at the MAC Lab and the Fort Lee Regional Archaeological Curation Facility (RACF) are now active and available on tDAR. Making this wealth of archaeological information accessible was made possible through “Evaluating a Cooperative Approach to the Management of Digital Archaeological Records (ECAMDAR)” – a project funded by the Department of Defense Legacy Program. The two collections contain a wealth of archaeological data from 23 Army and Navy bases and facilities in the Virginia, Maryland and Washington, DC area that has been collected over the past three-plus decades.
The purpose of the ECAMDAR project–led by Sara Rivers Cofield, the Federal Curator at the MAC Lab–was to evaluate tDAR as a potential repository for the DoD’s digital archaeological records. The study used collections from the MAC Lab at Jefferson Patterson Park and Museum (JPPM), and the RACF at Fort Lee. Together, the MAC Lab and RACF curate collections from 25 DoD installations. Existing digital data files from these installations were submitted to Digital Antiquity where digital curators, led by Jodi Reeves Flores, checked files, migrated them to current digital format standards (as needed), drafted metadata for each file, redacted very specific site location data (as needed), and uploaded the files to tDAR. In total, 6,889 files/17.6GB from 23 installations were added to tDAR where they are now protected in perpetuity as irreplaceable records of archaeological sites and are accessible in accordance with 36 CFR Part 79 and DoD regulations.
The project was designed to test whether the features and functionality of tDAR is appropriate and sufficient to manage DoD data in a manner that is secure, cost-effective, and of benefit to the military mission. The process demonstrated that tDAR is capable of meeting these requirements and could be adopted by bases and facilities throughout the DoD. The tDAR software and features are flexible enough to handle files from many different installations. The results were positive, so comments regarding DoD-wide implementation are included in the project report submitted to the Department of Defence Legacy Program and now under final review for approval.
Digital Antiquity would like to thank Rivers Cofield and the project participants from the different installations for their time and commitment to the project, as well as the DoD Legacy Program for recognizing the importance in preserving and making accessible digital archaeological materials.
The Society for American Archaeology supports a generous tDAR benefit for student members, and time is running out to take advantage of this offer for 2014! All SAA student members are eligible for a voucher that allows them to upload three files (totaling 30MB) to tDAR, valued at $150. This is a wonderful opportunity to develop good digital archiving habits, and to preserve and make accessible your archaeological information. Students have used these in a variety of ways. For example, Angela Huster used hers to archive the data associated with her publication in Advances in Archaeological Practice. Saul Hedquist turned a class paper into a conference poster, and archived the data set, the poster, and the references in tDAR.
You need not be as far along with your research as Angela or Saul were for their tDAR projects. For example, you might archive data, photos, maps, or reports gathered to support your Master’s thesis or dissertation research, even if these materials aren’t final or the results aren’t yet published. Photos, maps, and field notes or reports may be ready to archive now — even before you’ve completed your analysis or interpretations. If you plan to add to your data sets in the future you can upload a current copy to tDAR for safekeeping, and replace the file when you have new data. If you haven’t yet published the information you can embargo the file in tDAR, which will prevent others from downloading it until a date specified in the future.
If you aren’t sure what to put into tDAR, or how to get started we encourage you to sign up for one of our online seminars through SAA’s Online Seminar Series. Introduction to Archaeological Digital Data Management is offered on February 12th, 2015 from 12-2PM EST. Introduction to Digital Repositories for Archaeological Materials: tDAR (the Digital Archaeological Record) is offered on September 28th from 2-3PM EST, and is free to SAA members. Read more about and register for these and other online seminars offered by SAA here.
To take advantage of your SAA student member benefit please email email@example.com and request your tDAR voucher for 2014 before January 31st, 2015. If you haven’t yet registered to become a tDAR member visit tDAR.org to sign up. Then head over to tDAR’s pricing page (core.tdar.org/cart/add), enter your voucher number in the “Redeem Code” field, and click “Next: Review & Choose Payment Method.” Your credit will be added to your account and you can begin uploading files!
Completely re-designed data integration tool:
For those unfamiliar with tDAR’s integration tool, it provides a means by which users who have uploaded data sets to tDAR can combine multiple data sets with different schema and coding conventions into a unified, shared data set.
Adding data sets is simpler.
Users can search for data sets that are bookmarked or integrate-able (that is, having one column mapped to an ontology), as well as by keyword.
It is easier to add integration columns via a drop-down menu.
Once data sets have been added, if they share a mapping to an ontology, users can add an “Integration Column.” Integration columns allow users to further filter the resulting data set by selecting terms.
Once an integration column has been created, users can then “filter” results by selecting values from the ontology. tDAR display’s a checkmark where each data set has actual values.
A new “count” column type that represents count data in data sets.
A screenshot of a count column being added to an integration.
It’s easier to add a display column.
A display column being added to the integration. Each data set can supply one column to be included in a display column.
We’ve added better documentation of the integration in the excel output.
The Integration Results preview screen which includes a summary table, a preview of the results, and a link to download the full results.
- Integrations can now be saved and restored.
- We’ve improved support for larger integrations 10+ data sets
- The results of integrations are now sorted by the selected integration columns.
